Copper Ore Types: Sulfides vs. Oxides | Investing News …

Copper ore types: Oxides. As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. However, in some cases low-grade copper oxide ores can still be economically mined because they can be processed at a lower cost than copper sulfide ores.

ores are either treated through standard sulphide flotation, sulphidisation or flotation followed by acid leaching. The performance of each of these process routes depends on the degree of oxidation as predicted by the proportion of acid soluble copper present in the ore. Process parameters must be aligned to optimize the recovery and grade profile.
